Figures 1 to 6 The utility model discloses a sliding screen assembly 0, including winding unit 1, flexible screen 2, support plate 3, fixed base 4 and sliding link mechanism 5.

Figure 5 Figure 6 The utility model discloses a sliding screen assembly 0, including winding unit 1, flexible screen 2, support plate 3, fixed base 4 and sliding link mechanism 5. Figures 1 to 6 ​​, the sliding link mechanism 5 slides reversely to drive the support plate 3 to move reversely, that is, to drive the support plate 3 to move from Figure 5 and Figure 6 the unfolded position shown in the figure to Figure 3 and Figure 4 the intermediate position shown in the figure to Figure 1 Figure 2 the folded position shown in the figure, thereby driving the winding unit 1 to wind the flexible screen 2, so that the flexible screen 2 is folded.

[0038] In the embodiment, one end of the flexible screen 2 is wound on the winding unit 1, and the other end is a free end 21 which is hinged to the support plate 3. During the unfolding and folding of the flexible screen 2, the winding unit 1 provides a certain tension to the flexible screen 2 to ensure that the flexible screen 2 is taut.

[0039] In some possible embodiments, the winding unit 1 is a roller which is connected to a driving motor, and the driving motor drives the roller to roll to wind and unwind the flexible screen 2.

[0040] In other possible embodiments, the winding unit 1 is a winding spring which has an automatic reset function and can automatically wind the flexible screen 2.

[0041] With the above technical solution, since the flexible screen 2 is hinged to the support plate 3, when the sliding link mechanism 5 slides forward and reversely to drive the support plate 3 to move forward and reversely, the flexible screen 2 also moves relative to the support plate 3. When the flexible screen 2 is unfolded, the flexible screen 2 is in close contact with the support plate 3, and the support plate 3 provides a support force to the flexible screen 2 to enhance the strength of the flexible screen 2 and prevent the flexible screen 2 from collapsing to affect the screen display effect.

[0042] The utility model discloses a sliding link mechanism 5 movement realizes the unfolding and folding of the flexible screen 2, and the structure is simple. The sliding screen assembly 0 also does not need to arrange the movement track of the unfolding and folding of the flexible screen 2, and the appearance is simple and beautiful.

[0043] In some possible embodiments of the utility model, reference is made to Figure 1 , Figure 3 and Figure 5 The fixed base 4 includes a sliding panel 41. The sliding panel 41 is provided with a first sliding groove 42 and a second sliding groove 43.

[0044] The sliding link mechanism 5 includes a link part and a sliding part.

[0045] In some possible embodiments, the sliding link mechanism 5 is an integrally formed structure, that is, the link part and the sliding part are integrally formed.

[0046] The connecting rod part comprises a first connecting rod 51, and the sliding part comprises a first sliding block 52, a connecting arm 53 and a second sliding block 54. The two ends of the connecting arm 53 are fixedly connected with the first sliding block 52 and the second sliding block 54 respectively. One end of the first connecting rod 51 is fixedly connected with the second sliding block 54, and the other end of the first connecting rod 51 is hingedly connected with the support plate 3.

[0047] The first sliding block 52 is located in the first sliding groove 42 and can slide along the first sliding groove 42; and the second sliding block 54 is located in the second sliding groove 43 and can slide along the second sliding groove 43. The first connecting rod 51 drives the support plate 3 to move forward and reversely through the forward and reverse sliding of the first sliding block 52 in the first sliding groove 42 and the second sliding block 54 in the second sliding groove 43.

[0048] In the embodiment, the first sliding block 52 and the second sliding block 54 can be columnar. The shape of the first sliding block 52 and the second sliding block 54 is not limited in the utility model, as long as the first sliding block 52 and the second sliding block 54 can slide in the first sliding groove 42 and the second sliding groove 43 respectively.

[0049] Since the first sliding block 52 and the second sliding block 54 can slide in the first sliding groove 42 and the second sliding groove 43 respectively, the support plate 3 can move according to a predetermined movement track, so as to meet the needs of users. The sliding screen assembly 0 can realize a larger movement range in a smaller space through the sliding mechanism instead of a fixed mechanism (such as a fixed connecting rod mechanism, one end of the connecting rod is fixedly connected with a fixed base, and the other end is fixedly connected with a support plate), and is suitable for application scenarios with limited space. Moreover, the forward and reverse sliding of the first sliding block 52 and the second sliding block 54 can drive the support plate 3 to realize bidirectional movement, increase the movement flexibility of the mechanism of the sliding screen assembly 0, and can adapt to different operation requirements. In addition, the first sliding block 52 and the second sliding block 54 are fixedly connected through the connecting arm 52. This design keeps the sliding screen assembly 0 having good structural rigidity and improves the stability of the whole mechanism.

[0050] In some possible embodiments of the utility model, with reference to Figures 1 to 6 , the first sliding groove 42 is arc-shaped and recessed forward. The second sliding groove 43 is located behind the first sliding groove 42 and is oblique, as shown in Figure 2 , the included angle between the direction from the bottom end to the top end of the second sliding groove 43, that is, the direction B shown in the figure, and the direction from back to front of the sliding screen assembly 0, that is, the direction from back to front or the direction Q1 in the figure, is an acute angle a.

[0051] In the embodiment, the front-to-back direction is as shown in Figures 2 to 6The Q direction shown in the figure has two directions. The direction from back to front is the Q1 direction, which is also the direction closer to the flexible screen 2 in the entire mechanism of the sliding screen assembly 0. The direction from front to back is the Q2 direction, which is the direction farther away from the flexible screen 2 in the entire mechanism of the sliding screen assembly 0.

[0052] The arc-shaped first slide groove 42 enables the sliding linkage mechanism 5 to move in both vertical and horizontal directions, allowing the support plate 3 to achieve a large range of motion within a small space. The shape, position, and angle design of the first slide groove 42 and the second slide groove 43 all affect the movement angle and trajectory of the support plate 3. This design allows the sliding screen assembly 0 to achieve multiple movement modes, such as translation and angle adjustment, increasing the functionality of the assembly.

[0053] In this embodiment, reference Figure 1 The forward movement of the first slider 52 is along direction A1 as shown in the figure, and the reverse movement of the first slider 52 is along direction A2 as shown in the figure. Correspondingly, the forward movement of the second slider 54 is the same as the forward movement of the first slider 52. The reverse movement of the second slider 54 is the same as the reverse movement of the first slider 52. At the same time, during the forward and reverse movements of the first slider 52 and the second slider 54, the extension direction of the connecting arm 5 also changes, so as to drive the support plate 3 to move along a predetermined trajectory, thereby driving the winding unit 1 to unwind and rewind the flexible screen 2, so that the flexible screen 2 unfolds and retracts.

[0054] Specifically, such as Figure 2 As shown, when the flexible screen 2 is retracted, the first slider 52 is located at the apex of the first groove 42, and the second slider 54 is located at the apex of the second groove 43. At this time, the connecting arm 53 is located above the second groove 43, and the angle between the direction of the connecting arm 53 from the second slider 54 toward the first slider 52 and the direction from back to front, i.e., the Q1 direction, is an acute angle.

[0055] refer to Figure 1 and Figure 2 When the first slider 52 moves from the apex of the first groove 42 along the positive direction (A1), the second slider 54 also moves from the apex of the second groove 43 along the third direction (A1). Figure 1 The movement is in the C1 direction as shown in the diagram.

[0056] refer to Figure 3 and Figure 4 When the first slider 52 continues to move along the positive direction, i.e., the A1 direction, and moves to the midpoint of the first groove 42, i.e., the position corresponding to the maximum curvature of the first groove 42, the second slider 54 moves along the third direction, i.e. Figure 1 The object moves in the C1 direction as shown to the bottom point of the second slide 43. (Reference) Figure 4At this time, the position of the connecting arm 53 is basically parallel to the second slide groove 43, and the angle between the direction of the connecting arm 53 from the second slider 54 toward the first slider 52 and the direction from back to front, i.e., the Q1 direction, is an acute angle. Figure 2 The angle between the two shown is shown.

[0057] refer to Figure 5 and Figure 6 When the first slider 52 continues to move along the positive direction, i.e., the A1 direction, and reaches the bottom point of the first groove 42, the second slider 54 moves along the fourth direction, i.e. Figure 1 The C2 direction shown in the figure moves to the apex of the second slide 43.

[0058] like Figure 6 As shown, when the flexible screen 2 is unfolded, the first slider 52 is located at the bottom point of the first groove 42, and the second slider 54 is located at the top point of the second groove 43. At this time, the connecting arm 53 is located below the second groove 43, and the angle between the direction of the connecting arm 53 from the second slider 54 toward the first slider 52 and the direction from back to front, i.e., the Q1 direction, is an acute angle.

[0059] As described above, when the first slider 52 moves from the apex of the first groove 42 along the positive direction (A1), the positive movement of the second slider 54 is first along the third direction (C1) and then along the fourth direction (C2). During the positive movement of the first slider 52 and the second slider 54, the extension direction of the connecting arm 5 also changes, so as to drive the support plate 3 to move along a predetermined trajectory and to unfold the flexible screen 2. Similarly, when the first slider 52 moves from the bottom point of the first groove 42 along the negative direction (A2), the negative movement of the second slider 54 is first along the fourth direction (C2) and then along the third direction (C1). During the negative movement of the first slider 52 and the second slider 54, the extension direction of the connecting arm 5 also changes, so as to drive the support plate 3 to move along a predetermined trajectory and to retract the flexible screen 2.

[0060] In some possible embodiments provided by this utility model, the sliding screen assembly 0 includes a second connecting rod 6, one end of which is hinged to the fixed base 4, and the other end is hinged to the support plate 3. The forward and reverse sliding of the sliding linkage mechanism 5 and the forward and reverse rotation of the second connecting rod 6 drive the support plate 3 to move forward and reverse, thereby causing the flexible screen 2 to move first along the arc trajectory G11 and then along the approximately straight trajectory G21 when unfolded, and to move first along the approximately straight trajectory G22 and then along the arc trajectory G12 when retracted.

[0061] The sliding linkage 5 slides forward and the second linkage 6 rotates forward, driving the support plate 3 to move forward, and causing the flexible screen 2 to first move along the path shown in the image.Figure 6 The arc trajectory G11 is shown. The sliding linkage 5 moves again along the arc trajectory G11 shown. Figure 6 The approximately straight trajectory G21 is shown. The sliding linkage 5 moves reversely and the second linkage 6 rotates reversely, which drives the support plate 3 to move reversely and makes the flexible screen 2 move along the approximately straight trajectory G22 shown first and then along the arc trajectory G12 shown. Figure 6 The approximately straight trajectory G22 is shown. The sliding linkage 5 moves again along the arc trajectory G12 shown. Figure 6 The arc trajectory G12 is shown.

[0062] In some possible embodiments of the utility model, referring to Figure 1 , Figure 3 and Figure 5 , the other end of the first linkage 51 is hinged to the top of the support plate 3. The other end of the second linkage 6 is hinged to the bottom of the support plate 3. The first linkage 51 and the second linkage 6 are respectively hinged to the top and the bottom of the support plate 3, which helps to disperse and bear the load from the support plate and can effectively transmit force and movement.

[0063] In some possible embodiments of the utility model, the distance from the first sliding block 52 to the other end of the first linkage (i.e. the end hinged to the support plate 3) of the sliding linkage 5 is greater than the distance from one end (i.e. the end hinged to the fixed base 4) to the other end (i.e. the end hinged to the support plate 3) of the second linkage 6.

[0064] In this way, the sliding linkage 5 has a longer force arm, which can generate a larger torque at the bottom of the support plate 3, so that the support plate 3 can be pulled and lifted with only a small force to drive the support plate 3 to move. This torque amplification effect makes the entire sliding screen assembly 0 more labor-saving when the flexible screen 2 is unfolded and folded.

[0065] The length difference of the sliding linkage 5 and the second linkage 6 and their connection mode with the support plate 3 allow the support plate 3 to move between different angular positions. By sliding the sliding linkage 5, the angle of the support plate 3 hinged thereto can be changed, so that the support plate 3 moves according to the predetermined trajectory and angle.

[0066] In some possible embodiments of the utility model, referring to Figure 1 , Figure 3 and Figure 5 , two sliding linkages 5 are arranged along a first direction. Two second linkages 6 are arranged along a second direction. The first direction is parallel to the second direction. The two first linkages 51 are arranged between the two second linkages 6.

[0067] Referring to Figure 1 , Figure 3 and Figure 5The first direction and the second direction are both parallel to the fifth direction, i.e., the D direction shown in the figure. Figures 2 to 6 The first direction and the second direction are both perpendicular to the front-rear direction, i.e., the Q direction shown in the figure.

[0068] In some possible embodiments provided by the utility model, the first connecting rod 51 and the second connecting rod 6 are in an arc shape and protrude in a direction away from the fixed base 4. In this way, the complex and limited space in the automotive interior (such as the automotive on-board center console) can be avoided.

[0069] In some possible embodiments provided by the utility model, referring to Figure 1 , Figure 3 and Figure 5 , the sliding screen assembly 0 comprises a first synchronous rod 71 and a second synchronous rod 72. The two ends of the first synchronous rod 71 are respectively connected with the first sliding block 52 on the two sliding connecting rod mechanisms 5; the two ends of the second synchronous rod 72 are respectively connected with the second sliding block 54 on the two sliding connecting rod mechanisms 5. The first synchronous rod 71 and the second synchronous rod 72 both extend along the fifth direction, i.e., the D direction shown in the figure, and the first synchronous rod 71 is parallel to the second synchronous rod 72.

[0070] In some possible embodiments provided by the utility model, referring to Figure 2 , Figure 4 and Figure 6 , the sliding screen assembly 0 comprises a plurality of support guide rolling bodies 8. The plurality of support guide rolling bodies 8 are distributed along part of the movement track of the flexible screen 2 and are used for supporting the flexible screen 2 and guiding the forward and reverse movement of the flexible screen 2.

[0071] In this embodiment, the sliding screen assembly 0 comprises a support table (not shown in the figure). The plurality of support guide rolling bodies 8 are arranged between the support table and the flexible screen 2. The plurality of support guide rolling bodies 8 are arranged at the joint of the arc track G1 and the approximately straight track G2 of the flexible screen 2, and the plurality of support guide rolling bodies 8 are in rolling connection with the flexible screen 2.

[0072] When the support plate 3 drives the free end 21 of the flexible screen 2 to be unfolded, the winding unit 1 unwinds the flexible screen 2, and the unwound flexible screen 2 is in close contact with the plurality of support guide rolling bodies 8. The plurality of support guide rolling bodies 8 roll in place to support the flexible screen 2 and prevent the flexible screen 2 from collapsing, and the arrangement direction of the plurality of support guide rolling bodies 8 guides the flexible screen 2 to move along the arc track G11 and the approximately straight track G21. At the hinge joint of the support plate 3 and the free end 21 of the flexible screen 2, the free end 21 of the flexible screen 2 is pulled by the support plate 3 and moves along the approximately straight track G21 to unfold the flexible screen 2.

[0073] Similarly, when the support plate 3 drives the free end 21 of the flexible screen 2 to fold, the winding unit 1 winds the flexible screen 2, the wound flexible screen 2 is in contact with the plurality of support guide rolling bodies 8, the plurality of support guide rolling bodies 8 roll in place to support the flexible screen 2 to prevent the flexible screen 2 from collapsing, and the arrangement direction of the plurality of support guide rolling bodies 8 guides the flexible screen 2 to move along the approximate straight track G22 and the arc track G12. At the hinge between the support plate 3 and the free end 21 of the flexible screen 2, the free end 21 of the flexible screen 2 is pulled by the support plate 3 and moves along the approximate straight track G22 to fold the flexible screen 2.
